Patent JP-S62251728-A (JP)
Title: Optical switch
Inventor: AOYAMA TSUTOMU
IPC: G02F1/31
Filed: 1986-04-25
Abstract: PURPOSE:To make switching of optical paths without relying on the property of polarization of light inputted fro an optical fiber, by switching the optical paths under the switching condition of TM waves. CONSTITUTION:The light from an optical fiber 17 is separated into TE waves 27 and TM waves 28 by means of a double-refracting material 19 after image transformation by a lens 18. The TE waves 27 are changed to TM waves by means of a 90 deg. optical rotator 21 and passed through the 1st optical switching element 13 and the TM waves 28 are passed through the 2nd optical switching element 14. At both optical switching elements 13 and 14 the optical paths are switched to waveguides 15c and 16c. The TM waves passed through the waveguide 15c and the TE waves which are changed from the TM waves by a 90 deg. optical rotator 26 after passing through the waveguide 16c are joined together at a double-refracting material 24 and coupled with the optical fiber 22 on the other side. Thus the optical paths of this optical switch 11 are switched to each other under the switching condition of the TM waves without relying the property of polarization of light inputted from the optical fiber on the input side.

Title: Soft start circuit
Inventor: OGAWA SEIJI
IPC: G05F1/10
Filed: 1987-04-17
Abstract: PURPOSE:To extend a rise time and to shorten a fall time by connecting a switch between a power supply and a drain electrode of an FET, connecting a source electrode to a Zenner diode and connecting a capacitor to a gate electrode. CONSTITUTION:When the switch is closed, current charges the capacitor C11 from the drain of the FET through the course of the source, resistor R11 and the capacitor C11. Thereby, voltage between both the ends of the capacitor C11, i.e. output voltage E0, is almost linearly increased. When the source voltage of the FET reaches the Zenner voltage of the Zenner diode D11, almost all the source current of the FET flows into the diode D11, but a part of it continuously charges the capacitor C11 through the resistor R11. Thereby, gate potential is continuously increased against the source up to a state the potential difference between the source and gate reaches to 0V. Thereby, current flowing the drain and source of the FET is continuously increased and then stopped as a saturated current (IDSS). When the switch SW1 is opened, charge accumulated in the capacitor C11 starts to be discharged. At that time, the discharge course is a serial circuit consisting of the resistor R11 and a load RL, R11>RL is formed and the charge is discharged at a time constant determined by R11XC11.

Title: Gate circuit for gate turn-off thyristor
Inventor: YUYA SHIYUNICHI
IPC: H03K17/73
Filed: 1981-06-18
Abstract: PURPOSE:To unburden the duty of a Zener diode, by connecting a saturable reactor parallel with the Zener diode for turn-off connected between the gate and cathode of a gate turn-off thyristor. CONSTITUTION:When a transistor 7 is turned on, the gate and cathode of a GTO12 is forward-biased and the GTO12 is turned on. When the GTO12 is to be turned off, a transistor 8 is turned on. Then, reverse current flows from a power supply 2 to the cathode and the gate and the GTO12 is turned off. Although current flows to a Zener diode 15 clamping a voltage between the cathode and gate of the GTO12, when a saturable reactor 16 is saturated with a voltage generated across the diode 15, the current flows to the reactor 16. Thus, the loss due to the diode can be reduced.

Abstract: PURPOSE:To improve probability of focusing by repeating preliminary irradiation and range finding for several times until focusing can be obtained, and charging a main capacitor fully when the prescribed number of times of preliminary irradiation and range finding are performed. CONSTITUTION:A flash light emitting part 1 performs the preliminary irradiation of an object when light intensity distribution is measured, and a light emission control part 2 controls light emission when the preliminary irradiation is performed by the flash light emitting part 1. A light emission number of times counter part 3 counts the number of times of light emission of the flash light emitting part 1, and a focal distance detecting part 4 detects the focal distance of a photographic system. Furthermore, a charge control part 5 controls the charge of the flash light emitting part 1, and a charge voltage detecting part 6 detects a charging voltage controlled by the charge control part 5. A control part 7 repeats measurement for prescribed number of times until the focusing can be obtained when the charge voltage detected by the charge voltage detecting part 6 shows a light-emittable voltage, and performs the charge of the flash light emitting part 1 when no focusing can be obtained by the preliminary irradiation for the prescribed number of times, and controls so as to perform the measurement and the charge for the prescribed mumber of times.

Title: Data communication equipment
Inventor: KIDO NAOHARU
IPC: H04M11/00
Filed: 1991-04-02
Abstract: PURPOSE:To avoid a time loss due to unconditional reply with a call waiting phone by allowing the operator to decide whether the call waiting phone replies an incoming call or the current communication is continued without any replay when the call comes to the call waiting phone. CONSTITUTION:A call waiting phone signal sent from an exchange 9 is detected by a call waiting phone detection section 13. The detection signal is fed to a notice section 14, an off-hook detection section 15 and a retransmission command detection section 17. The notice section 14 replies the detection signal and requests a command to the operator as to whether the operator replies the call waiting phone signal or sends picture information again to an opposite party during communication without reply. When it is detected that the operator hooks off the handset, the call waiting phone signal is replied through the hooking. Moreover, when it is detected that a re-transmission command switch 19 is depressed, the picture information is sent again. The processing after the detection of the call waiting phone signal is implemented based on the command of the operator in this way.

Title: Paper box for rolled film
Inventor: KAI HISAO
IPC: B65H35/00
Filed: 1990-04-12
Abstract: PURPOSE:To make the title box suitable for industrial mass production and to decrease only its elastic repulsion without reducing strength by a method wherein a half cutting process in which cutting is done up to a middle part of thickness of a board paper is applied to an inward folding line formed by a rear plate and a lid body, and film making resin is applied to a half-cutting processed part. CONSTITUTION:Usually folding line press is provided on a border line between a rear plate 3 and a lid body 5, but in this case, instead of or in addition to the folding line press, half cutting process is provided. Namely to a degree of not cutting off a board paper which is a box material, the board paper is cut to a depth of the middle part of a thickness of the board paper. As a result, the paper becomes thin at this part and elastic repulsion of the paper itself drops down. Thus, after opening a lid, only if a hand draws off the lid, the lid drops down firmly on an opening part of a container. In addition, the half-cutting processed part is coated with film making resin for reinforcement. As the film making resin, polyvinyl chloride or stylene- butadiene resin, polyvinylidene chloride or ultraviolet hardening resin of the like is available. A ridge line 10 formed by the rear plate 3 and the lid body 5 is a part which is applied with the half-cutting process and further reinforced with film making resin.
